It becomes shall constitute a front view frame shape, the lower connection member, connecting with the connecting means on the facing surfaces of the left and right struts.

  With such a configuration, the lower portions of the left and right support columns are reinforced by the lower connecting member having a frame shape when viewed from the front, so that the strength and rigidity of the lower portion of the frame are increased, and the article mounting fixture wobbles in the left-right direction. Is prevented.

(2) In the article mounting fixture in which a shelf is attached to a frame formed by connecting the upper and lower portions of the struts spaced apart to the left and right with the upper connecting member and the lower connecting member facing in the left-right direction, The material has a frame shape in a front view in which the left-right dimension is substantially equal to the separation dimension of the opposing surfaces of the left and right struts, and the lower connecting material is connected to the opposing surfaces of the left and right struts by connecting means, Is composed of a pair of left and right upper connection fittings having an upward hook and a pair of left and right lower connection fittings having a downward hook, and the left and right upper connection fittings and the lower connection fitting are at least one of them. One of them can be moved in the vertical direction, and is attached to the upper and lower ends of both end portions of the lower connecting member, and the hooks of the upper connecting bracket and the lower connecting bracket are fitted into the engagement holes provided on the inner surfaces of the left and right columns. Match An upper connecting bracket and lower connection fitting, by moving in a direction relatively away by clamping means, engaging the respective hook engagement hole.

FIG. 1 is a perspective view of an embodiment of a work table which is an example of the article mounting fixture of the present invention, FIG. 2 is a front view of the same frame only, and FIG. 3 is an enlarged exploded perspective view of the frame. .

  The work frame 1 is a pair of left and right columns made up of a square tube with its lower end fixed to the upper surface of the rear end of the base leg 2 facing in the front-rear direction (hereinafter, described with reference to the right front side of FIG. 1). 3, 3, a lower connecting member 4 having a rectangular frame shape in a front view connecting the opposing surfaces of the lower portions of both supports 3, and an upper connecting material connecting the opposing surfaces of the upper ends of both supports 3. It consists of five.

A large number of engagement holes 6 in two rows on the left and right sides are arranged on the front surfaces of the left and right support columns 3 and 3 at regular intervals in the vertical direction.
Directly above the lower connecting member 4, on the front surfaces of both columns 3, a wiring duct 7 having a U-shaped cross section facing upward is seen from the side. Is attached so as to be detachable and changeable in height by engaging with a plurality of engaging holes 6 inside both the columns 3.

  Just above the wiring duct 7, a pair of brackets 8 (the right one is not shown) is provided on the front surfaces of both columns 3, and a plurality of engaging claws (not shown) protruding from their rear ends are provided. The racks 9 are detachably attached by engaging with the plurality of engagement holes 6 inside the support columns 3, and shelf boards 9 are fixed to the upper surfaces of the brackets 8.

  On the front side near the upper side of both columns 3, a shelf plate 10 smaller than the shelf plate 9 is provided with engaging claws (not shown) at the rear ends of the side plates 11, 11 fixed to both side surfaces thereof. By being engaged with a plurality of engagement holes 6 inside both struts 3, they are attached so as to be detachable and changeable in height.

  Engaging claws (not shown) at the rear ends of the side plates 13, 13 that are fixed to both side surfaces of the lighting device 12 and that face obliquely upward are attached to the front surfaces of the upper ends of the both columns 3. By engaging with the plurality of inner engagement holes 6, it is detachably attached.

  The lower connecting member 4 described above has a pair of upper and lower horizontal cages 14, 14 made of square tubes whose left and right dimensions are substantially equal to the dimensions between the opposing surfaces of both supports 3 and whose front and rear dimensions are shorter than that of the supports 3. And a pair of left and right vertical rods 15 and 15 made of square tubes whose upper and lower ends are fixed by welding so that the outer surfaces and the front and rear surfaces are aligned with each other on the opposing surfaces of both side end portions thereof. The both side ends of the upper and lower reeds 14, 14 are opened.

As shown in FIGS. 3 and 4, the lower connecting member 4 joined in a frame shape is composed of a pair of left and right upper connecting brackets 16, 16 and lower connecting brackets 17, 17. It is connected to the lower facing surface of.
The left and right upper coupling brackets 16 and 16 can be inserted from both ends into the upper horizontal bar 14 by a bottom piece 16a facing in the left-right direction and a pair of upper and lower pieces 16b and 16b rising from the front and rear edges. The upper hooks 18 and 18 are connected to the outer ends of both upward pieces 16b.
As shown in FIG. 4, a nut 20 is fixed to the lower surface corresponding to the through hole 19 formed in the central portion of the bottom piece 16 a of each upper coupling metal 16 by welding.

  The left and right lower connecting brackets 17 are formed in a lower part of the lower horizontal bar 14 by a bottom piece 17a having a front and rear dimension slightly larger than that of the horizontal bar 14 and upward pieces 17b and 17b rising from the front and rear edges. It is formed in a U shape that can be more fitted in a side view and has hooks 21 and 21 that are hooked downward at the outer ends of both upward pieces 17b.

  Next, with reference to FIG. 4, the point which connects the lower connection material 4 to the right and left support | pillar 3 is demonstrated. In addition, since the connection structure of the lower connection member 4 to the right and left support | pillar 3 is left-right symmetric, only the right side is shown in figure.

  First, the left and right lower connection fittings 17 and 17 are fixed to both side end portions of the lower horizontal bar 14 in the lower connection member 4 as follows. That is, after the lower connecting bracket 17 is externally fitted to the side end portion of the lower horizontal flange 14 so that the hook 21 protrudes outward, the bolt is inserted from below into the through hole 22 provided in the bottom piece 17a. 23 is formed in the lower surface of the side end portion of the horizontal bar 14, and is screwed into the screw hole 24 to be tightened (see FIG. 4).

  Next, left and right upper coupling fittings 16 are inserted into the side ends of the upper horizontal bar 14 from the side, and the upper surface of the side edge of the upper horizontal bar 14 is inserted into the nut 20 on the lower surface of the upper coupling bar 16. The top end of the bolt 26 inserted from above is screwed into the through hole 25 provided in the upper part, and the upper connecting bracket 16 is temporarily fixed so as to be positioned in the middle part in the horizontal bar 14 (see the two-dot chain line in FIG. 4). .

  Next, before connecting the upper end portions of the left and right support columns 3 with the upper connecting member 5, the front and rear engagement holes 27, 27 in the form of longitudinal slits formed on the inner surfaces of the lower end portions of the support columns 3 (see FIG. 3). The hooks 21 and 21 of the left and right lower coupling fittings 17 in the lower coupling member 4 are dropped and engaged with the lower edge of the lower coupling member 4, and the lower ends of the lower coupling member 4 are temporarily supported by the left and right columns 3.

  Next, the slit-like front and rear engagement holes formed on the inner side surfaces of the middle portions in the vertical direction of the left and right support columns 3 are made smaller than those of the lower engagement holes 27 and 27. The left and right upper coupling fittings 16 that have been temporarily fixed are inserted into 28 and 28 (see FIG. 3). This insertion operation can be performed by slightly tilting the both columns 3 outward. The vertical dimension of the engagement hole 28 is such that the hook 18 of the upper connection fitting 16 can be inserted with a margin, and the height of the opening edge at the upper part of the engagement hole 28 is the hook of the lower connection fitting 17. In a state in which 21 is engaged with the engagement hole 27, it is aligned slightly below the upper surface of the upper horizontal bar 14, that is, as shown in FIG. Alternatively, it is positioned slightly below it.

Next, the bolts 26 are tightened, and the upper coupling fitting 16 is pulled up until the upper end thereof is in contact with or close to the lower surface in the horizontal cage 14. As a result, as shown in FIG. 4, the hook 18 is strongly engaged with the lower edge portion of the engagement hole 28, and the vertical force in the opposite direction acts on the support column 3 by the lower hook 21. Both ends of the lower connecting member 4 are firmly connected to the opposing surfaces of the left and right support columns 3 while preventing rattling in the vertical direction.
After the lower connecting member 4 is connected to the opposing surfaces of the left and right columns 3, the opposing surfaces at the upper end portions of both columns 3 are connected by the upper connecting member 5, whereby the assembly of the frame 1 is completed.

In this way, when the lower facing surfaces of the left and right support columns 3 and 3 are connected to each other by the lower connecting member 4 having a rectangular frame shape, the left and right support columns 3 made of rectangular tubes are connected to the left and right inner surfaces of the left and right support columns 3. The vertical rod 15 is brought into surface contact and the portion is reinforced, and the upper and lower horizontal rods 14 prevent wobbling in the left-right direction of the two columns 3, so that the strength and rigidity of the lower portion of the frame 1 are increased, and the entire frame 1 is increased. Is prevented from wobbling in the left-right direction.
Therefore, even if a large shelf plate 9 is attached to the front surfaces of both supports 3 just above the lower connecting member 4 and a heavy article is placed on this, there is a possibility that there will be any problem in the strength of the lower portion of the frame 1. The shelf board 9 is supported stably.

  The lower connecting member 4 is connected to the left and right support columns 3 by engaging the hooks 18 and 21 of the upper and lower connection fittings 16 and 17 with the engagement holes 28 and 27 on the inner surface of the support column 3, respectively. As a result, a relatively simple operation of simply pulling the upper coupling metal 16 upward is sufficient, and the work efficiency at the time of assembling the frame 1 is improved because it is not directly fixed to the support column 3 with a plurality of screws.

In addition, as shown in FIGS. 1-3, the wiring duct 29 which faces an up-down direction is provided in the right end part between the upper coupling member 5 in the upper coupling material 5 and the upper coupling material 4 at the right column. 3 is attached so as to be in contact with or in close proximity to the inner surface of 3.
The wiring duct 29 has a front duct forming member 30 whose vertical dimension is substantially equal to the dimension from the upper end of the support column 3 to the lower surface of the upper horizontal bar 14 in the lower connecting member 4, and a rear duct forming member 31 that is opposite to the front duct forming member 31. And.

  The front duct forming member 30 and the rear duct forming member 31 are respectively provided with side pieces 30a and 30a bent rearward and side pieces 31a and 31a bent forward on the both side edges thereof. By doing so, they are formed in a U-shape opposed to each other in plan view. Opposite side portions of the upper and lower ends of the side pieces 30a and 31a are notched along the vertical direction.

  As shown also in FIG. 5 which is an enlarged longitudinal sectional view, the front and rear end projecting dimensions of the front duct forming member 30 and the rear duct forming member 31 have the front and rear protruding dimensions, respectively. A mounting bracket 33 having a U-shape in plan view that is slightly smaller than the front and rear dimensions of the side pieces 30a, 31a in the portion 32 is fixed by welding or the like, and the lower half of the central portion in the left-right direction of the locking piece 33a that is perpendicular thereto. A locking groove 34 that opens downward is formed in the part.

A locking screw 36 is loosely screwed into the screw hole 35 because it is formed on both the front and rear surfaces of the right side end portion of the upper reed 14 in the lower connecting member 4 and the front and rear surfaces of the right end portion of the upper connecting member 5. ing.
Both the duct forming members 30, 31 are formed by dropping the locking grooves 34 of the upper and lower locking pieces 33 a in the front duct forming member 30 and the rear duct forming member 31 from above to be locked. The left and right side pieces 30a, 31a are provided on the right end between the upper connecting member 5 and the upper reed 14 in the lower connecting member 4 so that the left and right side pieces 30a and 31a face each other and face each other. It is detachably attached so as to sandwich the right end of the wiring duct 7 in the direction. In addition, the front and rear duct forming members 30 and 31 can be fixed by tightening the locking screw 36 after the attachment.

As a result, a through space 37 is formed between the facing surfaces of the front duct forming member 30 and the rear duct forming member 31 in the vertical direction, and the power cable of the illuminating device 12 is connected to the upper cut-off facing the front and rear. It can be inserted into the through space 37 from the notch 32, pulled out from the lower notch 32, and wired in the wiring duct 7 facing downward in the left-right direction.
In addition, a slit-like gap 38 is formed between the side pieces 30a and 31a facing each other so that a cable or the like can be easily inserted into the through space 37 from the side, It can be pulled out.

  As described above, in the above-described wiring duct apparatus, an article placement fixture such as a workbench can be used without changing the shape of the support column 3 that is generally used or performing any processing on the support column 3. In addition, since the through space 37 facing in the vertical direction can be easily formed and detachable, it can be easily removed when not in use.

  In addition, a plurality of left and right female screw holes 35 are provided in advance in the horizontal flange 14 and the upper connecting member 5 of the lower connecting member 4, and the locking screw 36 is screwed into the left and right female wires 35. The mounting position can be easily changed.

In the above-described embodiment, the lower connecting bracket 17 that connects the lower reed 14 in the lower connecting member 4 to the column 3 is externally fitted to the reed 14 from below and fixed by the bolt 23. A lower connecting bracket similar to the connecting bracket 16 may be inserted into the lower side ridge 14 in the upside down direction so that the hook 18 faces downward, and fixed with a bolt 23. At this time, the distance between the lower engagement holes 27 and 27 may be made equal to the distance between the upper engagement holes 28 and 28.
In this way, when the lower part is connected by the same connecting metal as the upper connecting metal 16, the lower connecting metal is not exposed to the outside, so that not only the appearance is improved, but the upper and lower connecting metal parts are separated from each other by the bolts 26. Since it can be moved in the opposite direction, the hook 18 can be firmly engaged with the upper and lower engagement holes 28 and 27.

In the above embodiment, the hook 18 of the upper coupling fitting 16 is engaged with the upper edge of the engagement hole 28, and the hook 21 of the lower coupling fitting 17 is engaged with the lower edge of the engagement hole 27. The hook 18 of the connection fitting 16 is a downward hook and the upper connection fitting 16 is moved downward to engage with the lower edge of the engagement hole 28, and the lower connection fitting 17 has the same shape as the upper connection fitting 16. The hook 18 may be engaged with the upper edge of the engagement hole 27.
At this time, the left and right dimensions of the upper connecting bracket 16 are made large, and the upper and lower connecting brackets are moved closer to each other by the bolts 26 inserted from the opposing surfaces of the upper and lower horizontal flanges 14 inwardly without interfering with the vertical rod 15. It may be moved to and fixed to the recumbent rod 14.
